The CAS management webapp is unavailable. NPE ERROR [org.apereo.cas.mgmt.services.web.AbstractManagementController] - java.lang.NullPointerException

[Krzysztof Kluczynski]

Hi,

I am getting an NPE  [org.apereo.cas.mgmt.services.web.AbstractManagementController] - java.lang.NullPointerException after a successful login to the CAS management webapp.

Both CAS and the CAS management webapp are configured to use LDAP.

Hello,

Can you tell me how did you make it work out. I have the same problem.

Thank you,
Cristina

[Olivier Calzi]

Hi,

I think that my current problem is also related.
Did you manage to get it working ?

Thanks

[Cristina Vlaicu]

I did not get it working. Please let me know if you find the solution.

Thank you,

Just guessing here, but I think I would first try trimming down the principal list values from:

cas.authn.ldap[0].principalAttributeList=sn:familyName,cn:casId,givenName,mail,memberOf,xxxUID

To maybe:

cas.authn.ldap[0].principalAttributeList=cn,xxxUID

Things that always exist in every ldap record.  My theory is one or more is null and throwing the NPE.

If that's not it, I would simplify my properties line by line restarting cas-management app each time until the NPE goes away.  Painful, I know, but other than reading the source code or paying a vendor like Unicon for support, not sure what else to try.

Good luck.
